I've been looking around for ways to mount bullet LEDs on my house and i prefere that the LEDs on the roof remain permanent. I'm also wondering how i could get the correct measurements to the rooflines so I can get the correct size of materials. Any help would be greatly appreciated

In my experience measuring will get you close, but not exact.  Strings and spacing are not exact.  3" or 4" spacing only means that the length of wire from solder point inside the pixel to the solder point inside the next pixel is 3" or 4"  twists in wires and the way that they exit after waterproofing all adds up to being slightly off.  You should never ever order the exact number of pixels anyway.  Eventually you will need a replacement or two or more and colors isia;;u do not match well between different years of the same manufacturer let alone between manufacturers so we always order more than we need and save the rest for replacements or eventual use in another prop.  Besides it is nice to have some extras to play around with.

And to muddy the waters even further...

China uses the metric system so when they say 3" or 4" that's just appropriate. They are really 75mm and 100mm respectively, which is a bit shorter than actual inches and that adds up with stings of hundreds of pixels
